To all whom it may concern.-

Be it known that we, GEORGE RIEL and WILLIAM RIEL, citizens of theUnited States, residing at Manchester, in the county of Hillsboro and State of New Hampshire, have in- V vented certain new and useful Improvements in Guides for Sole- Sewing Machines; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains tomake and use the same.

This invention, which relates to guides for shoe-sole-sewing machines, is directed more particularly to improved means for adjusting the guide to effect variations in the line of stitching to accord with variations in the projecting portion of the sole.

The nature of the improvements will be readily comprehended, reference being had to the following detailed description and to the accompanying drawings, in which the invention is illustrated in its preferred form, it being understood that tions may be made therein without departing from the spirit of the invention as defined by the claims.

In the drawings, Figure l is a perspective View of a portion of a sole-sewingmachine and a guide-adjusting means embodying the invention. Fig. 2 is a plan view,the positions of the parts being shown in full and dotted lines. Fig. 3 is a vertical sectional view on line 3 3 of Fig. 2.

Referring to the drawings by numerals, 1 denotes the post of a sole-sewing machiue,and 2 is the throat-plate. The guide consists of a plate 3, adjustably supported on the throatplate by screws 4 4, which occupy longitudinally-disposed slots 5 5 in the plate 3, the forward end 6 of the plate being formed to provide a proper guiding-surface and the rearward end 7 being downturned and provided with a threaded hole 8. Ascrew 9, havinga thumb-head, is inserted in the hole 8 and bears at its inner end against the rear end of the throat-plate to limit the forward movement of the guide, such range of movement being, however, variable, accordingly as the screw 9 is adjusted. A jam-nut 10 serves to lock the screw 9 against accidental turning. At one side of thepost is secured, by means various modificaof a bolt 11, a plate 12, having at its rear end a laterally-bent portion 13 in a threaded hole in which is inserted a screw 14, forming'the pivot of a lever 15. This lever extends trans: versely across the guide and engages a. pin

16, projecting upwardly from the latter.

' normal position. The bolt 11 extends through the post and its ends project sufficiently to engage with the hooked ends of coiled springs 17 17, which extend at the sides of the post and have opposite ends hooked into holes pro- 'Vided in side extensions 18 18 of the plate 3.

The lever is moved by the knee or by the foot of the operator, and to this end there is provided a lever 19, pivoted by a pin to a bracket 20, secured to the bench and having one arm 21 provided toward its extremity with a squared opening engaging the squared end 22 ofthe lever 15.

Movement of the lovers 19 and 15 effects rearward movement 'of the guide from the normal position of the latter, which is predetermined by adjustment of the screw 9, and by reason of the multiplied leverage provided such movement of the parts is effected by a slight manual pressure and is therefore readily controlled. V

The nature of the improvement enables its attachment to existing machines without modification, and the parts being few in number and simply constructed there is no liability to disorder.

We claim as our invention- 1. In a sole-sewing machine, the combination of a post, a throatplate thereon, a guideplate having a downturned rear end and mounted on the throat-plate to be moved longitudinally, a shoulder on the guide-plate, a pivoted lever in engagement with said shoulder, a knee or foot operated lever con'hected with the aforesaid lever, a set-screw at the downturned end for limiting the movement of the guide-plate, and a spring for retracting the guide-plate after movement.

2. In combination, a post, a throat-plate on the post, a plate at one side of the post, a

bolt securing the side-plate, and passed In testimony where'cf'we afiix our-signathrough the post, a. guide-plate movable on tures in presence of two witnesses. V the throat-p1ate,springs connecting the guide- GEORGE RIEL.
